Other Parts Discussed in Thread: AM3517

Hi,

What is the operating voltage of AM3517 GPMC,
the datasheet "SPRS550" page 93 provides Switching Characteristics for only  1.15V,1.0V and 0.9 V,
where can I find the Switching Characteristics for 3.3V.

Thankyou in advance.

    Those values are not available yet.  Actually, those tables in the datasheet are a typo.  They should only describe 1.8V and 3.3V interfaces.  1.15, 1.0, and 0.9 are not valid I/O voltages for AM3517.

    Hi,

     

    Any updates?

    With regardance to reading data through "GPMC/Multiplexed NOR Flash – Asynchronous Read" operation

    I would like to know that, at what exact time the data should be fetched from the external device.

    Please let me know if there is a detailed timing diagram about reading data.

    Figure 6-11. seems to be insufficient.

     

    Thankyou.
